Background: Although the epidemiology of road traffic accidents (RTAs) and their determining factors have been extensively investigated and debated in Iran, yet there is no data regarding socioeconomic inequalities in mortality from RTA in Iranian context. Since effective interventions to control, management and diminish the negative influence of RTAs would require understanding of numerous contributing factors, including the inequalities We aimed to quantify for the first time the socioeconomic differential in mortality or injuries from RTAs.

Study design: A cross-sectional study.

Methods: Overall, 50755 died and injured people from RTA from Mar 2015 to Feb 2016 were evaluated. The data were taken from traffic police department in Iran. We calculated concentration index (CI) to measure socioeconomic inequality in traffic-related mortality & injury. Data were analyzed using Stata software.

Results: The mortality and injury rate from accidents was 1130.80 per 10000 accidents. The concentration index was negative for mortality rate (-0.11) of RTA, indicating the higher concentration of the rates among deprived groups.

Conclusion: People with low socioeconomic level were more at risk for fatal accidents and injuries. Therefore, specific interventions on road safety should be delivered in the deprived drivers which uses from low safety level vehicles.
